Skin tags and moles are two very common skin growths which many people will be familiar with. They can appear on various parts of the body, and most of the time, are usually harmless. While the two skin growths share similarities and are often mistaken for one another, there are also distinct differences in appearance, development, and treatment options.
Here’s everything you need to know about moles and skin tags, including the characteristics, causes, and treatment options for each.
What are moles?
Moles are small dark skin growths that occur when melanocyte (pigment-producing) cells grow in clusters. They usually vary in size, colour, and shape: moles may be round or oval, flat or raised, and have hairs or a smooth texture. Many moles appear at birth, but it’s also common for moles to develop over time with age.
Moles are usually caused by genetics, but other factors such as sun exposure can increase someone’s likelihood of developing moles. While moles are usually nothing to worry about, some have the potential to develop into melanoma, a form of skin cancer. It’s important to monitor moles and seek support if you notice any size, shape, or colour changes.
What are skin tags?
Skin tags are soft, small growths which are usually skin-coloured or slightly darker. Unlike moles which form in deeper layers of the skin, skin tags tend to occur when extra cells develop on the surface of the skin. This forms a small tag-like structure which looks as if it is just hanging off the skin. Skin tags typically form in places where the skin folds, such as the neck, armpit, or groin. Tags are generally painless and harmless, but may become irritated if caught on clothing, for instance.
Genetics can play a role in the development of skin tags, but tags can also be caused by skin rubbing on skin, meaning people who are overweight are more likely to develop skin tags. Hormones, medication, and certain medical conditions like diabetes may also influence overall likelihood.
Removing moles and skin tags
Most skin tags and moles do not need removing, but occasionally, they might. For instance, some people may remove skin tags or moles for cosmetic reasons, or if they are causing discomfort. Moles usually also need removal if they are showing signs of potential cancer.
Moles and skin tags have several different treatment options, and a dermatologist will be able to identify the best method for you based on your skin condition, location, and individual needs.
Mole removal technique could include:
- Surgical Shave: The mole is gradually shaved off using a sharp blade, leaving a small wound that heals naturally.
- Curettage: A spoon-shaped implement called a curette is used to gently scoop out the mole.
- Excision: The mole and a small patch of skin is removed using various surgical tools. If the mole is relatively big or deep, stitches may be necessary.
- Laser: A focused beam of light is pointed at the mole which destroys the cells.
Similarly to moles, skin tags can also be removed via a surgical shave. Skin tags might also be removed by:
- Cryotherapy: Also known as “freezing”, this technique involves using liquid nitrogen to painlessly destroy the cells within the skin tags.
- Diathermy: An electrical current and needle are used to heat and burn the skin tags.
